BAILER.

Application `:filed May 8, 1922. Serial No. 559,361.

To all whom t may concern:

Be it known that l, ALEXANDER BorN'roN, a citizen of the United States,and resident of San Antonio, in the county of Bexar and State of Texas,`have invented certain new and useful improvements in Bailers, of whichthe following, is a speciiication.

This invention relates to bailers especially adapted for removing suchmaterial as mud, slush and muddy water from oil and water wells.

Briefly stated, an important object of this invention is to provide awell bailer havingD a plurality of material discharge openings in thesides thereof with greater area than the cross sectional area of thebailer so that the material may be readily and conveniently discharged.

Further the invention aims to provide a bailer having simple meansywhereby the openings in the inner andouter sleeves mayr be aligned forthe purpose of discharging the contents.

Also the invention forming the subject matter of this application isprovided with oppositely arranged longitudinally extending openings, oneof which may be employed as an inlet means for a stream of Asteam orwater and the other openingl employed as an outlet for the melted mud,hot water and steam., thereby preventing the hot water and. steam fromreturning onto the hands of the operator., as is the case with thebailers now in general use,

A further object is to provide ya bailer having simple means wherebyheavy and stiff mud may be thrust out through one side of the bailer bymeans of a suitable tool,`in serted from opposite side so that the mudabove may drop into position between the openings and be subsequentlythrust out in same manner.

The invention forming the subject matter of this application also aimsto provide a bailer having means whereby the downward thrust of the samemay be employed as a means for forcing the mud or other material intothe bailer.

A further object is to provide a bailer in which the partscannot beaccidentally disconnected when lowered in a well and which isextremelysimple and reliable in use.

Other objects and advantages of the invention will be apparent duringthe course of the followingf description.

ln the accompanying drawing, forming;

a part of this application and in which like numerals are employed todesignate like parts throughout the same,

Figure l is a perspective of the bailer and a discharge member.

Figure 2 is a vertical section through the same.

Figure 3 is side elevation of the bailer.

F igure l is a section talren on line 4-*4 of Figure 2.

ln the drawing` wherein for the purpose of illustration is shown apreferred embodiment of the invention the numeral designates an outersleeve having its forward portion interiorly screw threaded as indicatedat 91 for engagement with the rear portion of bailer bottom 92. Thisbottom is, as illustrated in Figure 2 formed with an internal annularshoulder 93 upon which an annular valve seat 91lis mounted. las furtherillustrated in Figure 2, a flap valve 95 is pivoted as indicated at 96to the top of the valve sea-t and when mud is introduced into the bailerthe valve is elevated. However. the flap valve 95 serves as a positiveand reliable means for preventing; the escape of mud through the lowerend of the bailer. Yt will be observed that the valve seat and the valvedo not substantially decrease the cross sectional area of the inletportion of the bailer and consequently little resistance is offered tothe admission of mud inte the bailer. Further, the forward portion ofthe bailer'bot tom. is formed with lil-shaped recesses 9i which providea large inlet means at the lower end of the bailer and churn and mii;the mud.

ln carrying' out the invention an inner sleeve 98 is arranged within theouter sleeve and is limited in its rotation with relation to the outersleeve by means of a pin or set screw 99 which operates in an arcuatetransversely extending slot 100 in the outer sleeve.

In practical operation outer sleeve 90 will rotate upon inner sleeve 98by turning` upon threads 91.

yThe `slight longitudinal movement of the sleeve 98 when one sleeve isrotated on the other is permitted bythe fact that the set screw 99 isfreely received in the slot 100.'

The pin 99 not only serves as a means for limiting' the rotation of onesleeve with relation to the other but also serves as a means forpreventing longitudinal movement of one sleeve with relation to 'theother. in carrying out .invention the lower portion of the inner sleevev96 is exteriorly screwthreaded for engagement with the intermediateportion of the bailer bottom which as illustrated in Figure 2 is formedwith screw threads 102; The bailer bottom 92 cannot become accidentallydisconnected from the outer sleeve as there are approXimately 16threadsl to the inch at the connection 91 while there are 8 threads tothe inch at the connection 102. This would cause a binding between theparts as the result of any independent rotation ot the bailer bottom,which binding would prevent the loss or disconnection of the bailerbottom 92. It inner sleeve should become broken from bottom at threads91 the bottom would not be lost but would be lifted out of well by pin99, which thus becomes a fishing tool' in case oi a disconnected bottom.

In summarizing the connecting means of the various parts oi the bailer,it will be seen that the bailer vbottom 92 has threaded connection withthe inner and outer sleeves which prevent the bailer bottom 92 frombeing accidentally lost when in the well. The connection between theinner and outer sleeves and the bailer bottom co-operates with the pin99 to absolutely prevent the loss of the outer section or the bailerbottom. Should the connection 102 be broken warning of the fact will begiven by the hanging ofthe outer section 102 on the pin 99 whereupon thebroken connection may be quickly remedied by merely cuttingA new threadson bottom of inner sleeve 98.

The inner and outer sleeves 90 and 96 re` spectively are formed withelongated slots 105 and 106 respectively through which mud or othermaterial may be quickly discharged. There are two of the openings 105and two ot the openings 106 and these openings have a combined areagreater than the cross sectional area ot the bailer so that when theopenings are in registration the contents ot bailer may be quicklydischarged. lf the mud is thick and will not l'low readily a steam pipeor hose may be introduced into one of the openings 'formed by the slots105 and 106 for the purpose of melting the mud. In this case the steamhose is introduced through one of the openings and the mud tlows outthrough the other openings. 1t is thus seen that the steam will notreturn through the opening by which it enters. lll/'hen it is desired tobring the openings 105 and 106 into registration the lrnurled portions108 may be manually gripped and the outer sleeve rotated whereupon theinner and outer openings will be brought into registration for allowingdischarge of the mud.

The upper end of the outer sleeve 90 is formed with notches 161 whichare engaged by a tool employed for rotating the sleeves.

It however, it is not desired to manually rotate the outer section, thebailer may be.

introduced into a cylindrical discharge member 110 having its upper endflared as indicated at 111 so that the bailer will be self guided intothe cylinder.

The cylindrical discharge member 110 is provided with longitudinallyextending` slots 114 adapted for registration with the slots 105 and106. The bailer bottom 92 and the outer sleeve 90 are formed withaligned grooves 116 for the purpose of receiving a guide pin 117 carriedby the cylindrical discharge member. Figure 3 illustrates that thegroove 116 begins at the apex oit' one ot the V-shaped recesses 97 whichincidentally serves as a means for guiding the pin 117 into the groove.

Figure 3 also illustrates that the outer sleeve 90 is provided with aspiral or curved groove 120 which communicates at its forward end withthe rear end oit the groove 116 and said spiral groove 120 is adapted toslidably receive a second guide pin 122. Then the pin 122 is receivedwithin the spiral groove the outer sleeve is slightly rotated so thatthe foremost longitudinally extending groove 116 will be in a positionto receive the pin 117.

In operation when the bailer is introduced into the cylindricaldischarge member 110 the longitudinal groove 116 lirst receives theguide pin 122 and then the spiral groove 120 receives the guide pin 122and` simultaneously with the entrance ofthe guide pin 122 into thespiral groove 120 the foremost pin 117 is received in the longitudinallyextending grooves 116 whereby the parts are rotated so as to bring theslots 105 and 106 into registration.

In operation no time is lost in dumping as when the device is introducedinto the cylindrical container 110 the openings in the inner and outersleeves are automatically brought into registration whereupon thecontents of bailer may be readily discharged. llVhen the apparatus isintroduced into the well the thrust of the same is utilized as a meansfor forcing the mud or other material into the inlet end of the bottom92 and consequently the bailer is rapidly filled.

In churning the bailer bottom 92 may be bumped against the bumper 125carried by the lower portion of the cylindrical discharge member 110,the babbitt bumper 125 is mounted upon a bottom plate 126 torniL ing apart of the cylindrical discharge member.

In summarizing. it will be seen that the mud is introduced into thebailer at the lower end of the same and that it is discharged laterallyof the bailer so that the discharge opening is not in any. wayrestricted when churning the bailer whereby the maximum area for thedischarge of the material is provided for. i

It is to be understood that :teem elf the invention herewith shown anddescribed is to be taken as a preferred example of the same and thatsuch minor changes in arrangement and construction of parts may be madeas Will remain Within the spirit of the invention and the scope of whatis claimed.
